7 July 19

I discovered that today is the birthday of Joseph Marie Jacquard (1752-1834), a French weaver and merchant. He is credited with developing the programmable loom, and the Jacquard name has long been associated with repeating patterns woven into fabric. My tie's repeating paisleys represent a modern product based on Jacquard's work. His programming for the loom was based on a sequence of punched cards, directing the operation of hooks to guide the yarn. This idea eventually became the basis for all sorts of calculating machines, down to the 20th-century "modern" computers receiving their instructions from decks of punched cards.
